冲床离合器是精密冲床的重要组成部分，它安装于冲床传动飞轮与曲轴之间，和冲床刹车配合作动，在运行过程中离合器和刹车是同步的，即离合器合动作，刹车放开，离合器分动作，刹车抱死。精密冲床均采用干式离合器，其构造包括离合器主体、离合斜键、离合杠杆、压盖，其中离合斜键和离合杠杆的转轴分别安装装于离合器主体与压盖的轴孔中，离合斜键的钩状凸起与离合杠杆的短臂的位置相对，在离合器主体的折弯柱壁的弹簧孔中装有压缩弹簧，离合器的运行原理是：当离合斜键在弹簧作用下顶入传动飞轮的相应的楔形键槽中而实现传动接合。在实际运行中，离合器通过控制刹车片的开合来决定滑块的行程，刹车片放开时，冲床的凸轮机构便开始工作，滑块下行，当任意一点刹车片收紧后，凸轮控制的轴便得到一个空行程，滑块回升。
冲床使用的离合器主体采用优质高牌号的球墨铸铁，离合器性能稳定。压缩弹簧，密封件等选用原装进口，大大提高的离合器的稳定性和使用寿命；同时在刹车/离合器的摩擦块设计具有耐磨性极强，非石棉的优质组合材料精铸而成，保证冲床滑块能在任意位置停止。
离合器的作用不可忽视，这也就决定了它在日常使用过程中的检修必不可少，在这里我们分两点来讲解离合器的维修：
第一、精密冲床离合器/刹车间隙调整
（1）调整的原因及必要性：冲床长时间运转作业后，摩擦片会有磨损，这时会影响刹车时间及刹车角度，造成刹车与离合器同步出错，此时必须加以调整。
（2）离合器/刹车器间隙是否合适的检测方法：
A．将冲床滑块寸动置于下死点位置，按下主电机停止按钮使飞轮呈静止状态（主电源仍NO的状态）。
B．向冲床飞轮一侧推刹车板，让离合器/刹车器之间间隙显现，以厚薄规量测间隙大小（离合器/刹车器正常间隙为1.5-2mm）。
C．如果超过此间隙则必须增加垫片进行调整（测量出的间隙减1.5（mm）=增加垫片厚度）。
第二点、精密冲床离合器常见故障及排除方法：
